Question

我正在开发一个桌面应用程序，它将执行自动测试用例。用户可以从GUI中选择执行类型：按功能/按场景/按tagName。现在，我正在使用maven并在CMD中执行命令来执行测试用例，我想切换到TestNG执行，但是我需要从配置文件CucumberOptions动态设置

@CucumberOptions(features = { "src/test/resources/features/" }, tags = { "@Test3" }, glue = { "stepdefinitions" }, plugin = { "listeners.ExtentCucumberFormatter:" })
public class TestNGRunner extends AbstractTestNGCucumberTests {
}

但是CucumberOptions需要一个常量表达式，我无法设置它们。

有什么方法可以做到吗？

您可以通过命令行参数传递黄瓜选项：

您可以列出您所使用的黄瓜版本的可用选项   使用。

传递--help选项以打印出所有可用配置   选项：

java cucumber.api.cli.Main --help

或者：

mvn test -Dcucumber.options="--help"

您还可以使用标签来指定要运行的内容。

配置选项也可以被覆盖并传递给任何   通过Cucumber.options Java系统属性进入赛跑者。

例如，如果您正在使用Maven并希望运行   标有@smoke的场景：

mvn test -Dcucumber.options="--tags @smoke"

提供了将选项传递给黄瓜的其他机制。一些跑步者

注意：这是来自 Java，我从 Eclipse 运行，而不是命令行。并不是说如果你知道自己在做什么，就会有巨大差异，但仍然......

我有一个 Excel 电子表格，其中每一行都包含一个角色和一个屏幕子集，并且我已经用 @tag 场景（及其相应的 Java/Selenium 代码片段）完成了我所有的 Gherkin 功能文件，这些文件测试了一个屏幕。有些角色只有 4 个屏幕；有些多达 46 个。我不想创建 24 个（可能更多）不同的 Cucumber Runners（Excel 电子表格中的每一行一个）。我首先尝试通过编辑 CucumberOptions 注释的 tags 属性来动态更改现有 Cucumber Runner 上的标签（在 Java 中；这是可能的！），但我无法让它接受多个标签的字符串数组；只有个别标签。 :-( 然后我偶然发现了cucumber.api.cli.Main 是如何工作的，这让一切变得更容易。最重要的类是cucumber.runtime.Runtime 和cucumber.runtime.RuntimeOptions。我将跳过所有POI 代码用于读取 Excel 文件，但重要的部分如下：

import org.junit.Test;
import org.junit.internal.TextListener;
import org.junit.runner.JUnitCore;
import org.junit.runner.Result;

import cucumber.api.CucumberOptions;
import cucumber.api.SnippetType;
import cucumber.runtime.ClassFinder;
import cucumber.runtime.Runtime;
import cucumber.runtime.RuntimeOptions;
import cucumber.runtime.io.MultiLoader;
import cucumber.runtime.io.ResourceLoader;
import cucumber.runtime.io.ResourceLoaderClassFinder;

public class MyRunner {

    /** Constructor */
    public MyRunner (String thisPath) {
           // This does all the POI stuff, plus making the data available to
           //   getCellData(sheet, columnName, row) (which you get to define). 
           // Any way that makes it return a dynamic value will work here.
    }   
 
    public static void main(String[] args) {
        MyRunner myRunner = new MyRunner ("src/main/resources/User Roles.xlsx");
        myRunner.runRunner();
    }

    public void runRunner() {
        String[] newTags = { "@Login" }; 
        String sheetName = "Sheet1";
        int rowCount = this.getRowCount(sheetName);
        String role = "";
        String userId = "";
        String password = "";
        //For each row in the Excel file (row 1 is column names)
        for (int i=2; i<rowCount; i++) { 
            System.out.println("\n run loop i: " + i);
            int rowNumber = i-1;
            role = this.getCellData(sheetName, "User Role", rowNumber).trim();

            // I had to do some indirection here because customer who edits the
            // Excel file does not want to see Tags, but uses Screen titles.
            // So I had to map it.
            ArrayList<String> tagList = this.screenTitlesToTags(screens);
            System.out.println(rowNumber + ". Check " + tagList.size() + " screens.");
            runOneRow(rowNumber, role, userId, password, tagList);
